Rapid clamping and casting mechanism applied to field of casting

Abstract

The invention discloses a rapid clamping and casting mechanism applied to the field of casting. The rapid clamping and casting mechanism comprises a base, a mold with a casting port at the top is fixedly mounted on the base, a sleeve for placing the mold is rotatably mounted at the top of the base, a plurality of through grooves are formed in the outer side of the sleeve, sliding sleeves are rotatably mounted in the through grooves, first connecting rods slidably connected with the sliding sleeves are rotatably mounted at the top of the base, and the free ends of the multiple first connectingrods are rotatably connected with rollers tangent to the surface of the mold. According to the rapid clamping and casting mechanism, when the sleeve rotates clockwise, the first connecting rods are driven to rotate outwards relative to the mold, the mold is loosened and taken out conveniently, when the sleeve rotates anticlockwise, the first connecting rods are driven to rotate inwards relative tothe mold, the mold is clamped, the mold is fixed conveniently, meanwhile, automatic centering of the mold can be achieved, it is guaranteed that the central axis of the mold and the central axis of the sleeve are collinear, therefore, accurate communication between a casting funnel and the casting port is guaranteed, and molten iron splashing or overflowing during casting is avoided.

Description

technical field [0001] The invention relates to the technical field of quick clamping and casting mechanisms, in particular to a quick clamping and casting mechanism applied in the casting field. Background technique [0002] Casting is a method of processing iron products; in the early stage of casting, high-temperature liquid iron was injected into the mold under normal pressure, polymerized and solidified to form a product with the same shape as the inner cavity of the mold. In the prior art, iron products During casting, the molten iron is poured into the funnel through the casting pipe, and the molten iron is introduced into the mold from the casting port through the funnel. [0003] The existing casting mechanism still has the following disadvantages during use: [0004] First of all, because the internal stress generated by the flow of molten iron will drive the mold to shift, therefore, the mold needs to be fixed, and the casting port on the mold must be aligned wit...

AI Technical Summary

Problems solved by technology

[0004] First of all, because the internal stress generated by the flow of molten iron will drive the mold to shift, therefore, it is necessary to fix the mold and make the casting port on the mold align with the casting pipe. The clamping and fixing of the existing mold is usually done manually Fix the mold and align the sprue with the pouring tube. However, there are inevitable errors in manual fixing, which leads to the inaccurate alignment of the sprue with the pouring tube. During the casting process, there are problems of molten iron splashing or overflowing;

[0005] Secondly, after the mold is cast, due to the high temperature of molten iron, the surface temperature of the mold and the structure supporting the mold is high, which brings inconvenience to the removal and placement of the mold, and there is a danger of scalding the staff if there is a slight carelessness
